- Tighten the bolts 1 - 12 in the sequence shown. Tighten the bolts to their respective torque:
- Tighten M6 mounting bolts to 11 N.m (8 ft. lbs.).
- Tighten M8 bolts to 23 N.m (17 ft. lbs.).
- Tighten M10 bolt to 50 N.m (37 ft. lbs.).
- Repeat the tightening sequence until the proper torque has been met.
- Spin water pump to be sure that pump impeller does not rub against timing chain case/cover.CAUTION:
A number or letter is stamped into the tongue of constant tension clamps (4). If replacement is necessary, use only an original equipment clamp with matching number or letter.
